Have I missed some progress on this topic? FWIW I can take care of
RISC-V support in kexec-tools, I even received a VisionFive 2 board
from RVI last year specifically to help with kexec.

I merely don't want to duplicate efforts or "steal" someone else's
project. Is RISC-V support in kexec-tools an orphaned project now?
